Switch to standard customise via ConfigBuilder for Configuration/DataProcessing

[davidlange6]

Changed the Reco.py in DataProcessing to use the standard customise functionality in ConfigBuilder for better support of unscheduled mode. Contents of fully dumped Tier0 configs are the same (and there are fewer differences between relval and Tier0 now)

Fixed bug in ConfigBuilder to apply unscheduled mode to both the dumped cfg and the process itself (the latter was missing before)
